Opportunistic routing protocols for Vehicular Ad Hoc Network (VANETs) and intelligent transportation system (ITS)

Abstract

The innovative technology Vehicle Ad Hoc Network (VANET) has received a great amount of interest in recent years. Due to rapid changes in topology and frequent disconnections, the efficient protocol for data routing between automobiles known as vehicle to vehicle (V2V) or vehicle to infrastructure (V2I) is hard to design for roadside infrastructure and automotive communication. The current VANET routing methods cannot deal with all traffic situations. This emphasized the development of an excellent routing mechanism. It is therefore important to determine the advantages and disadvantages of routing protocols that may be utilized to design or construct new routing protocols. In this article, the pros and disadvantages of VANET communication routing methods are addressed. An ad hoc car network that can set up all network devices to act as a host and a network router. Only nodes help each other to deliver information. Ad hoc vehicle networks were mostly temporary and less accessible infrastructure networks. The channel location and network connection instability diminish mobility and resource boundaries in the performance unit. Improve the relevant layering methods in other performance units used to stack communication through information exchange at certain other protocol levels. Everything is good ad hoc protocol routing for AODV. While the VANET is helping to provide efficient logistics and transport solutions, several difficulties must be addressed if an appropriate solution is to be found.
